Calibrated Peer Review (CPR) Method: Improving Student Descriptions Writing Skills in Madrasah Ibtidaiyah

Writing descriptions is a skill that has been taught in grade VI elementary schools such as MIN 6 Cilacap. The purpose of this study was to determine the effectiveness of the Calibrated Peer Review (CPR) method in students' writing learning. To answer the stated objectives, the research method used was pre-experiment using one class as the sample. The number of research samples was 40 students consisting of 21 male students and 19 female students. To see the effectiveness of the method in learning, researchers used the pre-test as a first step to measure students' abilities then post-test after giving the treatment. The results showed a significant effect on the pre-test and post-test scores where the initial score was a mean of 65.3 and the final score was an average of 72.5. There was a good effect on the results of learning to write student descriptions because of any significant development in teaching. Thus, the CPR method is effective in students' writing learning

Cultural Heritage in Social Studies Curriculum and Cultural Heritage Awareness of Middle School Students

The present study aimed to determine the cultural heritage elements in the social studies course curriculum in Turkey and the awareness of the middle school students about cultural heritage. In the study, the case study approach, a qualitative research design, was adopted. The study group was assigned with criterion sampling method, a purposive sampling approach. The study findings demonstrated that the cultural heritage elements were prominent in 4th grade and 5th grade curricula, respectively, and the least prominent in 6th and 7th grade curricula based on the social studies course curriculum achievements in Turkey. The middle school students associated cultural heritage with historical buildings the most in the physical historical heritage category and customs and traditions in the non-physical historical heritage category. Students mostly considered mosques as physical cultural heritage elements, followed by palaces, towers, castles, madrasahs, bridges, historical buildings, historical places, fountains, and customs and traditions, traditional dishes, oral traditions, performance arts, and crafts as non-physical cultural heritage elements. Students mostly reported that cultural heritage was important since it was inherited from ancestors, it allows us to learn the past events, it reflects us, not to forget the old times, it is our culture, it is our history, for the perpetuity of our state, to learn about past lessons, and they stated that the cultural heritage should be preserved by state protection, followed by allowing it to live on, raising awareness, claiming it as a heritage, remembering, warning, and punishment, respectively.

Prospective Clinicopathological Study of Penile Cancer Patients : A Single Institution Experience

Background: Carcinoma of the penis is an uncommon malignancy in Western countries but constitutes amajor health problem in many countries in Asia, Africa, and South America, where it may comprise up to10% of all malignancies.Materials and Method: 42 consecutive patients of carcinoma penis were treated from 2013 to 2015. Clinicaland pathological profies were recorded and studied prospectively.Results: 20/42 (48%) patients were of the age group 60 and above. majority of patients belonged to poorsocioeconomic status, 32/42 patients(76.1%). Glans of the penis was the most common site of presentationin 28/42patients(66.6%). The most common symptoms were pus discharge from the penile ulcer in 21patients(50%). 31/42 patients were chronic smoker or tobacco chewer. Inguinal lymph nodes were palpablein 24/42 (57%). The most common complication associated with Groin node dissection was lymphedema in19 patients (45.2%). 12/42 patients had inguinal lymph node metastasis in final histopathological examinationreport. 50 % patients had grade II primary tumor.Conclusion: Incidence of carcinoma penis peaks in the 6thdecade of life. Illiteracy, low socio-economicstatus and phimosis appear to be main predisposing factors for carcinoma of penis. Nodal metastasis wassignificantly associated with factors like T3 and high grade lesions (grade II & III). Complication rate relatedto groin node dissection is high, commonest being lymphedema.

Prospective Teachers’ Metaphoric Perceptions of Inclusive Education

The need for special education stems from “a group of neurodevelopmental disorders that begin in childhood”. Today, one of the main topics discussed with regard to the education of children with special needs is inclusive education. Inclusive education, which aims to ensure that they all receive the best quality of education, is an education model based on students’ sharing experiences with their peers. The purpose of this research is to examine university students’ perceptions of inclusive education through metaphor analysis. This study aims to determine how Faculty of Education students perceive the concepts of inclusive education, inclusive students, the family of inclusive student and teacher of the inclusive student. The study group consisted a total of 200 prospective teachers from different branches, including six participants from each grade level in the 2018-2019 academic year fall semester in Faculty of Education at Sivas Cumhuriyet University. 79 of the prospective teachers were male and 121 were female. The data obtained through interviews were analysed through content analysis and descriptive analysis. 12 different metaphors for inclusive education, 11 different metaphors for inclusive student, 9 different metaphors for the family of the inclusive student, and 11 different metaphors for the teacher of the inclusive student were produced.

Instructional Explanations of Class Teachers and Primary School Mathematics Teachers about Division

This study is a qualitative research which was conducted in order to reveal the instructional explanations of class teachers and primary school mathematics teachers working in state schools about division. A semi-structured interview form with three open-ended questions about division, prepared for this purpose, was examined by the experts. The semi-structured interview form inluded three questions asking the teachers to solve the long division operations of 3385: 13 = ?, 1238: 12 =? and 102102: 12 =? using the mathematical table of digits with a descriptive language as if they were telling the primary school students the solutions. While the first two questions were suitable with the 5th grade learning outcomes, the third question was suitable with a high level learning outcome. The main purpose of asking the 3rd question was to evaluate the instructional explanation of the teachers in a problem of different difficulty. The study group consisted of 34 teachers, 16 of whom were primary school mathematics teachers and 18 of whom were class teachers, working at central primary schools in a province located in Eastern Anatolia region of Turkey. The content analysis of the data showed that not all of the teachers could interpret the operation of division regarding the concept of digit accurately, and their division was result and reasoning oriented. However, it was found that few teachers made generalizations in a similar way. It was also seen that teachers who were at problem-solving level according to Kinach’s (2002b) comprehension level framework could not make sense of the logic underlying the division. In addition, the reason why zero (0) was moved to the quotient and when the divisor sought in remaining number should be completed by the teachers could not be clarified because they did not know the logic of the division.

MATHEMATICS TEACHER CANDIDATES NOTICE HOW

The aim of this research is to examine how mathematics teacher candidates' expressions about what they noticed in videos changed with video-clubs. The study group consisted of 5 teacher candidates studying in the 4th grade of Mathematics Education Department. The data of the study, which used focus group interviews that one of the qualitative research methods, consisted of students' notes while watching the videos and focus group interview video recordings. For the analysis of the data, content analysis that is one of the qualitative data analysis methods was used. Changes in the ways in which teacher candidates expressed the situations they noticed during the meetings were examined separately. It has been determined that teacher candidates’ expressions change according to the teacher they see in the video. If the teacher candidates like the teacher on video, they will use a more affirmative language, if they do not like the teacher in the next video, they will suddenly become critical and judgmental.

Failure of non-invasive continuous positive airway pressure as the initial respiratory support in very preterm infants: a multicenter prospective cohort study

Objective: To analyze the risk factors and the adverse outcomes of failure in non-invasive continuous positive airway pressure (CPAP) as the initial respiratory support in very preterm infants with gestational age at birth <32 weeks. Methods: This multicenter prospective cohort study was conducted from January 1, 2019 to December 31, 2019 based on the data from Shandong Neonatal Network (SNN). Perinatal information, clinical treatment, and the short-term outcomes of very preterm infants with gestational age at birth of 25-31+6 weeks in 30 neonatal intensive care units (NICU) in SNN were collected. The very preterm infants with non-invasive CPAP as the initial respiratory support were divided into the group of non-invasive CPAP failure and the group of non-invasive CPAP success. The difference in the risk factors between the two groups were tested by χ2 test or Fisher exact and the Mann-Whitney U test, followed by Logistic regression analysis for all the risk factors with statistically significant difference. Results: A total of 1 040 very preterm infants were included in this study, including 577 males (55.5%) and 463 females (44.5%). There were 195 cases (18.8%) with gestational age of 25-28+6 weeks, 845 cases (81.2%) with gestational age of 29-31+6 weeks, 81 cases (7.8%) with birth weight<1 000 g and 959 cases (92.2%) with birth weight≥1 000 g. Overall, the rate of CPAP success (n=902, 86.7%) was higher than that of CPAP failure (n=138, 13.3%). The incidence of CPAP failure was 24.6% (48/195) and 10.7% (90/845) respectively for infants with gestational age of 25-28+6 weeks and of 29-31+6 weeks. The Logistic regression analysis showed that smaller gestational age at birth, maternal gestational hypertension disease, and severe respiratory distress syndrome (RDS, grade Ⅲ-Ⅳ) requiring pulmonary surfactant (PS) for more than twice and fraction of inspired oxygen (FiO2)>0.30 after birth were independent risk factors for the failure of initially used non-invasive CPAP (OR=0.718, 1.847, 4.003, 6.712, 1.948; 95%CI:0.590-0.873, 1.130-3.018, 2.435-6.579, 3.160-14.259, 1.189-3.192; all P<0.05). The incidence of adverse outcomes in the group of failure was significantly higher than in the group of success, including death, neonatal pulmonary hemorrhage, moderate or severe broncho pulmonary dysplasia (BPD), and severe intraventricular hemorrhage (IVH) (OR=4.436, 26.393, 1.998, 4.545; 95%CI:2.106-9.344, 9.690-71.885, 1.031-3.875, 1.615-12.795; all P<0.05). Conclusions: The very preterm infants with gestational age at birth<32 weeks have a higher incidence of major adverse outcomes after the failure of initially used non-invasive CPAP. Smaller gestational age at birth, maternal gestational hypertension disease and severe RDS (grade Ⅲ-Ⅳ) requiring PS for more than twice and FiO2>0.30 after birth are independent risk factors for the failure of initially used non-invasive CPAP.

Latent classes of health risk behaviors in medical students and depressive symptoms

Objective To identify the latent classes of various health risk behaviors among medical students and further analyze the correlation between different classes and depression. Methods Using the method of convenient sampling, 2 014 medical students were selected from Anhui Medical University in October 2018. Self-designed online questionnaire were used to collect demographic data, health risk behavior (including smoking, drinking, suicide, sleep disorders, mobile phone dependence and lack of exercise) and depressive symptoms. Latent Class Analysis was used to cluster individuals. Logistic regression was provided to further analyze the association between health risk behaviors and depressive symptoms for the groups. Results The health hazard behaviors of medical students could be divided into three separate classes: substance dependence group (8.4%), mobile phone dependence group (22.4%) and low-risk group (69.2%). The distribution of health risk behaviors of medical students with different gender, major, grade, only child, father’s educational level, monthly living expenses, academic achievement and number of friends were statistically significant (χ 2 = 99.37, 19.07, 12.05, 6.64, 14.28, 19.35, 20.61, 26.39, P<0.05). The results of Logistic regression analysis showed that after adjusting for gender, major, grade, only child, father’s educational level, monthly living expenses, academic achievement and number of friends, the mobile phone dependence group was positively correlated with depressive symptoms (β = 1.75, P<0.01). Conclusion Different ratent classes of health risk behaviors have different correlation with depressive symptoms in groups. lt is suggested that school health workers should make individualized intervention plan for different types of health hazard behavior of medical students in the future educational activities, carry out stratified intervention, alleviate the symptoms of depression and promote the mental health of medical students. 【摘要】 目的 识别医学生多种健康危害行为的潜在类别,并进一步分析不同潜类别与抑郁症状的关联。 方法 采用方便抽样的原则,于 2018 年 10 月在安徽医科大学整群抽取 2 014 名医学生开展横断面调査。使用自编手机问卷,调査内容 包括一般人口学资料、健康危害行为评价以及抑郁症状。采用潜在类别分析方法分析吸烟、饮酒、自杀、睡眠障碍、手机依 赖、缺乏运动等 6 种健康危害行为潜在类别,采用 Logistic 回归方法进一步分析不同类别与抑郁症状的关联。 结果 医学生健康危害行为分为物质依赖组 (8.4%)、手机依赖组 (22.4%) 和低危风险组 (69.2%) 3 个潜在类别。不同性别、专业、年 级、是否为独生子女、父亲文化程度、每月生活费、学习成绩及朋友个数之间医学生健康危害行为分布差异均有统计学意义 (χ 2 值分别为 99.37, 19.07, 12.05, 6.64, 14.28, 19.35, 20.61, 26.39, P 值均<0.05)。Logistic 回归分析结果显示,调整性别、专 业、年级、独生子女及父亲文化程度、每月生活费、学习成绩以及朋友个数后,手机依赖组与抑郁症状呈正相关 (β=1.75, P<0.01)。 结论 医学生健康危害行为呈现类别分布,各潜类别健康危害行为与抑郁症状关联不同。提示学校卫生工作者在 今后的教育活动中应针对医学生不同类别的健康危害行为制定个体化干预方案,进行分层干预,缓解抑郁症状,促进学生 心理健康。

Evaluation of Underground Mineable Reserve in Presence of Grade and Commodity Price Uncertainties

The uncertainty-based mine evaluation and optimization have been regarded as a critical issue. However, it has received less attention in the underground mines than in the open-pit mines due to the diversity of the underground mining methods, and the underground mining parameters' complexity. The grade and commodity price uncertainties play essential roles in mining projects. Mine planning by not incorporating these uncertainties is accompanied by risks. The evaluation and risk assessment of the mine plans is possible through evaluating the mineable reserve in the presence of such uncertainties. In the present work, we evaluate the effects of grade and commodity price uncertainties on the underground mining stope optimization and the resultant mineable reserve. In this regard, the stope boundary is studied both deterministically and stochastically in the presence of the grade and price uncertainties. For this purpose, in this work, we implement the conditional simulation in order to generate equally probable ore reserve models. Furthermore, we optimize the stope boundary using the floating-stope algorithm in each realization. Several decision support criteria including the 'mineable reserve,' 'metal-content,' 'profit,' and 'value-at-risk' are defined to assist the decision-maker in uncertain conditions. Finally, a procedure is defined in order to consider two types of uncertainty sources simultaneously in underground mining. It will guide the decision-maker toward the most appropriate stope boundary that best fits the mining company's requirements. The procedure is implemented in a bauxite mine, and the optimal stope boundary is determined concerning the different criteria.

INVESTIGATION OF THE PREDICTIVE RELATIONSHIPS BETWEEN INTERNET ADDICTION, PERCEIVED EMOTIONAL ABUSE AND WELL-BEING IN ADOLESCENTS

In this study, it was aimed to examine the predictive relationships between adolescents' internet addiction and perceived emotional abuse and well-being. Correlational survey model was used in the research. The research group consisted of high school students studying in the 9th and 10th grades. This group was selected by simple random sampling method. 492 high school students, 271 girls (55.1%) and 221 boys (44.9%), participated in the study. In the study, Short-Form of Young's Internet Addiction Test, Short-Form-II of Perceived Emotional/Psychological Abuse Scale for Adolescents, Five-Dimensional Well-Being Model Scale for Adolescents, and Personal Information Form were used. Independent sample t-test, One-Way Anova, Pearson Correlation Coefficient, and multiple linear regression analysis techniques were used to analyze the data. According to the findings of the study, no significant difference was found between adolescents' internet addiction and gender variable. On the other hand, a significant difference was found between internet addiction and grade level of adolescents, the average daily internet use duration during the week, the average daily internet use duration at the weekend, internet use purposes, and the effect of internet use on sleep patterns. A positive, moderately significant correlation was found between adolescents' internet addiction and the score of emotional abuse perceived from mother and father. A moderately significant negative relationship was found between the internet addiction scores and well-being scores of adolescents. According to the findings of the study, it was found that perceived emotional abuse by parents and well-being scores were predictors (R = 0.411, R² = 0.17) on adolescents' internet addiction scores.

Objective To explore the influence of school mental health education combined with family intervention on the mental and physical health of middle school students. Methods A total of 280 students in six classes of the experimental middle school attached to Hebei Normal University were convenient selected as participants, and two classes in each grade were included in the experimental group and the control group. The experimental group received school mental health education and family intervention, while the control group only received school mental health education. The changes in GHQ, SCL-90 and common mental health problems were compared before and after intervention. Results The total score of GHQ-12 was (5.06±1.33) in the experimental group after intervention and (15.62±3.84) before intervention. The total score of GHQ-12 in the experimental group after intervention was significantly lower than that before intervention, and significantly lower than that in the control group ( t = 13.65, 8.39, P < 0.05). The scores for somatization, anxiety, depression, paranoia, interpersonal sensitivity, obsessive-compulsive symptoms, hostility, paranoia and psychosis in the experimental group were significantly lower than those in the control group ( t = −13.21–−6.71, P <0.05). After the intervention, the proportions of good interpersonal relationships, good parent-child relationships and after-school hobbies in the experimental group were 68.28%, 66.21% and 84.14%, respectively, which were significantly higher than those in the control group (35.56%, 40.74% and 51.85%, respectively), the proportions of people without intimate friends, early love and love after school were 9. 66%, 9. 66% and 4. 14%, respectively, which were significantly lower than those in the control group (20.74%, 24.44%, 21.48%) ( P <0.05). Conclusion School mental health education and family intervention can effectively improve the mental health of middle school students, improve their interpersonal relationships and promote their mental and physical health. 【摘要】 目的 探讨学校心理健康教育结合家庭干预对中学生心理健康的影响, 为促进中学生的心理健康提供参考。 方法 方便选取河北师范大学附属实验中学 6 个班级的 280 名学生作为研究对象, 将每个年级所选取的 2 个班级分别纳人 实验组 (145 名) 和对照组 (135 名) 。实验组采用学校心理健康教育并配合家庭干预, 对照组仅行学校心理健康教育。对 比两组学生干预前后的一般健康问卷 (GHQ) 评分、症状自评量表 (SCL-90) 评分及常见心理卫生问题的变化。 结果 实 验组干预后的GHQ-12总评分为 (5.06±1.33) 分, 干预前为 (15.62±3.84) 分, 干预后的 GHQ-12 总评分较干预前降低, 且低 于对照组干预后 ( t 值分别为 13.65,8.39, P 值均<0.05)。干预后实验组的SCL-90躯体化、焦虑、抑郁、偏执、人际关系敏 感、强迫症状、敌对、偏执、精神病性评分均低于对照组 ( t = −13.21~−6.71, P 值均<0.05)。实验组干预后人际关系好、亲子 关系好、课余爱好很多者占比分别为 68.28%, 66.21%, 84.14%, 均髙于对照组 (35.56%, 40.74%, 51.85%), 没有知心朋友、 有早恋、无课余爱好者占比分别为 9.66%, 9.66%, 4.14%, 均低于对照组 (20.74%, 24.44%, 21.48%) ( P 值均<0.05)。 结论 学校心理健康教育配合家庭干预可有效提髙中学生的心理卫生水平, 改善人际关系, 促进心理健康。

Correlation analysis between serum ferritin level and liver damage in acute stage of dengue fever

Objective: To investigate the correlation between serum ferritin (SF) level and liver damage in the acute stage of dengue fever. Methods: A retrospective study was conducted to analyze 171 cases diagnosed with dengue fever as dengue fever group and 130 healthy patients as control group in Hangzhou 3A grade hospital from July to December 2017. Clinical data, SF and liver function related indicators were collected from both groups: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) to analyze the correlation between liver damage and SF in patients with dengue fever. Results: ALT, AST, and SF levels were significantly higher in the dengue fever group than those in the healthy control group (Z = 11.553, 15.054 and 15.163, P < 0.001). SF levels were higher in the dengue fever combined with liver damage group than those without the liver damage group (z = 6.930, P < 0.001). However, there was no statistically significant differences in age, gender, peak body temperature, and history of liver disease (P > 0.05). In addition, Spearman's correlation analysis showed that SF was positively correlated with ALT, AST, and TBIL (r = 0.464, 0.531 and 0.315, P < 0.001). Among dengue patients with different SF levels, there were significant difference in ALT, AST levels and incidence of liver damage (H = 14.240 and 17.584, χ(2) = 49.547, P < 0.001). Patients with higher SF levels had higher ALT, AST levels and incidence of liver damage. Binary logistic regression analysis showed that hyperferritinemia (SF≥500 ng/ml) was the risk factor for dengue fever combined with liver damage (OR = 8.120, P < 0.001). Furthermore, ROC curve analysis showed that the AUC for SF to judge dengue fever combined liver damage was 0.846 (95% CI: 0.785-0.908), and the sensitivity and specificity when the SF cut-off value was 1 506 ng/ml were 74.8% and 83.3%. Conclusion: There is a certain correlation between the SF level and the degree of liver damage in acute stage of dengue fever patients, and hyperferritinemia is a risk factor for dengue fever combined with liver damage.

Clinical features of neurogenic bladder with vesicoureteral reflux in children

OBJECTIVE To study the clinical features of vesicoureteral reflux (VUR) in children with neurogenic bladder (NB), and to provide a reference for its early diagnosis and treatment. METHODS Clinical data were collected from 26 children with NB and urinary tract infection who were admitted to the Department of Pediatric Nephrology from January 2014 to December 2019. According to the presence or absence of VUR, the children were divided into a VUR group with 11 children and a non-VUR group with 15 children. Clinical features were compared between the two groups. RESULTS Compared with the non-VUR group, the VUR group had a significantly higher proportion of children with non-Escherichia coli urinary tract infection, hydronephrosis (the severity of hydronephrosis increased with the grade of VUR), abnormal 99mTc-DMSA renal scanning findings, elevated ratios of urinary albumin, urinary IgG and urinary transferrin to creatinine, increased residual urine volume, and increased detrusor leak point pressure (P < 0.05). CONCLUSIONS When NB children have the clinical manifestations of non-Escherichia coli urinary tract infection, hydronephrosis, abnormal 99mTc-DMSA renal scanning findings, glomerular proteinuria, increased bladder residual urine volume, and high detrusor leak point pressure, such children may already have VUR, and so diagnosis and intervention should be performed as early as possible.

A RESEARCH ON THE RELATIONSHIP BETWEEN ACADEMIC SELF PERCEPTION AND ACADEMIC SUCCESS

Bu araştırmanın temel amacı ortaokul yedinci sınıf düzeyindeki öğrencilerin akademik benlik algıları ile akademik başarıları arasındaki ilişkiyi belirlemektir. Akademik başarı; somut ve nesnesi olan bir kavramken, akademik benlik algısı soyut ve duyuşsal bir kişilik özelliğidir. Bu iki değişkenin birbirini hangi koşullar altında ne şekilde etkilediği ise birçok araştırmanın konusu olmuştur. Çalışmamız bu bağlamda insanın yaşam boyu geliştirip olgunlaştırmaya çalıştığı benlik bütünlüğü ve bunun parçalarına değinerek, akademik benlik algısı oluşturmanın başarıya giden yolda temel basamak olduğunu vurgulamaktadır. İnsanın kendi ile ilgili düşüncelerini içeren benlik kavramını ve bu kavramın akademik hayatla bağdaştığı akademik benlik algısını inceleyip öğrencilerimizin içsel süreçlerine ışık tutması açısından bu araştırma önemlidir. İlişkisel tarama modelinde desenlenen araştırmanın çalışma evrenini Bursa İlinin Mudanya İlçesine bağlı Hatice-İsmail Hakkı Kayan Ortaokulu yedinci sınıf öğrencileri oluşturmaktadır (N=90). Araştırmaya ilişkin verilerin toplanmasında Akademik Öz-yeterlik Ölçeği (Kandemir, 2010) kullanılmıştır. Veriler analiz edilirken IBM SPSS 22.00 istatistik paket programı üzerinden korelasyon ve t-testi analizi istatistiksel çözümlemesi uygulanmıştır. Korelasyon analizinde; öğrencilerin ölçek puanları ile mihver derslerindeki başarı notları veri olarak girilerek bu değişkenler arasında anlamlı bir ilişki olup olmadığına bakılmış ve cinsiyet değişkeninin, notları ve akademik benlik algıları ile ilişkisine de t-testi sonuçları ile karar verilmiştir. Araştırmanın bulguları genel olarak özetlendiğinde akademik benlik algısı puanları ile ders notlarının pozitif yönlü korelasyon gösterdiği tespit edilmiş ve cinsiyet değişkeninin öğrencilerin ders başarı notları ya da akademik benlik algılarıyla ilişkili olmadığı görülmüştür.
